Management of mandibular angle fractures using a 1.7 mm 3-dimensional strut plate.

AIM

We report our experience with the use of 1.7 mm 3-dimentional (3D) strut plate for the management of mandibular angle fractures.

METHODS

This prospective study enrolled 15 patients in whom mandibular angle fractures were treated with 1.7 mm 3D plate using trans-buccal trochar. Patients were evaluated at 72 h, 2 weeks, 6 weeks and 12 weeks for fracture stability, occlusion, soft-tissue swelling, infection and post-operative inferior alveolar nerve damage. Other complications like wound dehiscence, non-union, mal-union and hardware failure were also assessed.

RESULTS

In the immediate post-operative period, fracture instability was seen in 1 (6.7%) patient which resolved by 2 weeks. Mild occlusal discrepancy was also noted in 1 (6.7%) patient. Wound dehiscence was seen in 5 (33.3%) patients and all resolved by local measures. 1 (6.7%) patient developed post-operative nerve paraesthesia. Immediate post-operative radiographic evaluation demonstrated optimal reduction in all cases with no inferior border gaping. No case of infection, hardware failure, non-union and mal-union was noted.

CONCLUSION

Within the limitations of the study, 1.7 mm 3D strut plate was found to be effective for management of non-communited mandibular angle fractures.
